WAIT... Do you mean ATI? Because that whats printed on my Wii should check that again.

Oh man major fail on my part haha I've been up all night and thought that it said ATI so I highlighted it and made a comment... I've had a long night I should get out of here <_<

Won't be Treyarch.  Are you familiar with the new COD development schedule?  The series will alternate each year between the two developers: Treyarch and Infinity Ward.  Each developer will have ~2 years to work on the games.

Treyarch started work on CoD: WaW in early 2007 for a late 2008 release.
Infiinty Ward started work on CoD: MW2 in late 2007 for a late 2009 release.
Tryearch will begin work on CoD 7 sometime this month or next.
Infinity Ward will begin work on CoD 8 in late 2009/early 2010.
And so on....

As you can see, Treyarch already has their hands full in 2009 and can't make CoD: MW2 for Wii.

And you know this how?  Sounds like you're just assuming something with no real idea.  Activision calls the shots.  That's kinda how publishing works.  Publishers hire a developer to develop their IP for them.  Because the publisher owns the IP and pays the money, the developers work on their terms which includes which platforms it appears on (though it can be subcontracted to other studios if the publisher agrees the many developer doesn't have the time or resources for it like what happened with Quantum of Solace) and any TRC's they demand.

They will certainly push Cod:WaW hard with ads now. Even if it doesn't do stellar, they cannot afford to ignore the 42 million install base (at least 60-70m by the next CoD iteration)

The Wii has an API. It's just that developers were not bothering to push it.

@Viper

I was thinking that it would be Treyarch also. I know they alternate schedules, but I figured Treyarch has enough extra staff to Wii port every IW game on top of their own years. Don't they have teams that do multiple other projects every year and are under the same exact banner?

Onyxmeth, why would you assume that? Why would IW hire Wii developers with no intent to develop for Wii?

True that Treyarch may have the staff for it but that extra staff is typically used for other multi-console games and not for just a single console title. I wouldn't imagine that Activision would use the studio in that manner.

I don't see third parties crawling on their knees to the Wii.  The successful titles sell pretty well on the 360 and PS3.  Developers seem afraid to take a chance at losing money on the Wii versions.  Look at World at War, hopefully sales pick up, but it's not anything compared to their 360/PS3 sales.  As for wii owners convincing them, I have no clue what you're talking about.  If I was a third party developer i'd be doing 360/PS3 games.  It just seems like the Wii owners want the games, but when they come out nobody buys them.

Slavedemonxi, the problem is 2 fold.

1. 3rd parties ignore Wii so gamers that would normally buy 3rd parties ignore Wii.
2. 3rd parties finally give Wii some love but find not many receptive after being screwed over for so long.

However, the user base itself is growing in such shape and proportions that 3rd parties will have no choice but to start taking it more seriously.

But you're wondering why given the huge install base do the games not sell so well yet? Largely because the Wii version is usually an after thought. Poorly handled by an outsourced party and given little to no publisher fervor and marketing over the HD versions. If the publisher puts to little love into it, so little love will be given from consumers....metaphorically speaking.

When a multiplatform game leads development on Wii or is at least marketed just as much as the HD console iterations, the sales will show it.

If you'll note that ever franchise with multiple Wii entries is seeing marked improvement in sales for the latest entries. Each have the benefit of long sales trails on Wii such that EA sports games, CoD: WaW and others will all be million sellers. Something not expected from Wii from publishers, analysts and the media for the first year or so the Wii existed. Look at last generation. Madden 08 already outsold any Madden game on GC. CoD 3 outsold all the CoD games on GC. You get my point.

As the sales continue to increase, 3rd parties will put more effort into their Wii development. Not so much at the expense of the PS3/X360 but just to get a bigger chunk of what they've been missing so far.

 I think I'll take the realistic approach here without 3rd parties crawling on their knees, fanboyism and HD doom and gloom BS. Heres some of total development cost of some HD consoles and one Wii game:

http://www.neogaf.com/forum/showpost.php?p=14102879&postcount=250

Halo 3 costs 30 million not including the 300  staff they hired of course you'll pay for those guys not including advertisements and distribution rights and tax.

Lost Planet cost 20 million dollars not inclusing another 20 million for ads and such. And of course, sven didnt mentioned about the people they hired and distribution cost and tax.

The real kicker, Halo 2 costs 40 million dollars development cost alone, and thats for a last  gen console what more with these current gen consoles.

Red Steel cost 12.75 million dollars in development cost alone and Ubisoft says "development costs are in the range of a quarter to half of that required for PlayStation 3 or Xbox 360 development." woah woah woah there... WHAT?!! development cost Red Steel at that time costs 12.75 millon dollars and its a quarter of HD development cost at that time? You do the math...

Of course, as time goes by the development costs of HD consoles are becoming low but doesnt mean you cant say about Wii's develiopment cost either. Red Steel developed somewhere in 2005 or late 2004 3 or 4 years later, the development cost of Red Steel now could be only a fraction of what is in 2004 or 2005.

So which means 3rd parties must break 1 million to break even the development cost

Have you seen the credits of QoS? Any version? Because its multi platform so the teams working in other versions are also on Wii version added by Beenox. ITS LONG and I mean long. Thats the longest credit roll I've seen so far and thats a licensed game what more with main games. I think Im not exaggerating here when my estimates that people in the credit roll were in the hundreds.

Anyway, heres a article about it, Im not posting this because its too long to post this even the summary:
